IMPROVEMENT IN COMBINED BURGLAR AND FIRE=ALARMS.

Specification forming part of Letters Patent No. 120,261, dated October24, 1871; antedated October 13, 1871.

To all whom it may concern:

Be it known that I, LOUIS GLEBRICH, of Ottumwa, in the county ofWapelloand State of Iowa, have invented a new and Improved Fire andHotel-Alarm; and I do hereby declare that the following is a full,clear, and exact description thereof, which will enable others skilledin the art to make and use the same, reference being had to theaccompanying drawing forming part of this specification, in which-Figure l represents a side elevation, partly in section7 of my improvedalarm. Fig. 2 is a detail face view of the burglar-alarm attachment.Fig. 3 is a detail transverse section ofthe same. Fig. 4 is a detailside view of the fuse-holders. Fig. 5 is alongitudinal section of thesame. Fig. 6 is a side elevation ofy the interior alarm. Fig. 7 is anend elevation of the alarm-discharging apparatus. Fig. 8 is an endelevation of the alarm-setting apparatus. Fig. 9 is a detail horizontalsection of the setting-lever taken on the line a x, Fig. 8.

Similar letters of reference indicate corresponding parts.

This invention relates to a new apparatus for sounding an alarm in casefire breaks out in any part of a building within which it is set up. Theapparatus may also be connected with a burglaralarm, if desired. Theinvention consists in a new arrangement of alarm-setting 5 also, in anovel alarm-discharging apparatus, as well as in further combinationsand novel arrangements of parts, as hereinafter more fully described.

In the drawing, A represents the frame of the alarm-setting apparatus.Bis the frame of the alarm-discharging apparatus. These frames can bewholly or in part dispensed with if the several devices are secured tothe ceilings or walls of the building in which the alarm is set up. Theouter alarm-that is to say, the one to be heard in the street-consistsof a series of bells, O C, of greater or less size, suspended from apivoted frame, D, whose cross-arm a, is, by rods b b, connected withcrank-pins c c of a shaft, E. This shaft carries a pinion, d, meshinginto the teeth of a gear-wheel, e, which is mounted upon another shaft,F. The shaft F carries a drum, j', and weight g, which can be wound up,and which in un winding, if the shaft is not otherwise held, rotates thesame and E, thereby causing the frame D to vibrate and the bells C to besounded. The imwinding of the shaft F is prevented by a lever, G, lwhichenters between pins h h that project froni the wheel c. From the upperend of the lever G is suspended a forked lever, H, carrying a transverseroller, The forked lever straddles a T-rod, j, which projects iromabell-crank, I, when the lever G is set inclined, so that the roller iof Il iits under a Xed hook, Z, as indicated in Fig. 1, while the leverH, catching against projecting hooks m2 fm? of the rod j, as in Fig. 9,will also hold the bellcrank inclined as the apparatus is set; but asthere are powerful springs connected with the levers G and I, they willbe speedily withdrawn from said position by such springs if the cor'd m,attached to the upper end of I, is not held tense. This cord is, withone end, secured to a hook, a, of a rock-shaft, J, which hangs in thedischarging apparatus. Whenever the cord m is slackened the levers Grand I will be carried out of th eir inclined positions by theirrespective sprin gs in such manner that the lever Gr will be withdrawnfrom between the pins h and the shaft F released to swing the bells G. Across-bar, p, of the lever G may also be utilized for holding a hammer,q, away from a barrel, L, which is loaded with powder, so tha-t when thecord m is slackened the said hammer will be released and forced by aspring, 0, against the nipple of said barrel to explode the chargewithin the same. The rock-shaft J holds its hook 'n up by weightedcranks r r. It is, by arms s s, connected with a horizontal rod, t, overwhich' hooks a, that project from elbow-levers M M. are fitted. Thelevers M are connected each with a powerful spring or weight, o. Theupper arm of each lever M is connected with a cord, w, which isstretched. When the cord fw is separated the lever M is brought underthe influence of the spring V in such manner that it will fall back, andcatching over the rod t will swing the shaft J, so as to withdraw thehook n from the cord m and thereby set the alarm in action, as above setforth. The cords w w from the several levers M M are stretched withinthe several rooms of the building, and each cord w carries afuse-holder, N, shown in Fig. 4. This is a metal cylinder, made in twoparts, surrounding the cord, secured to the ends of and held together bystrings passing through cross-tubes .fr a: that project from thecylinders. Powder is through these cross-tubes brought int-o thefuse-holder N. Fuses lead also to the holder. Whenever in any part ofthe building fire breaks out the nearest fuse will be speedily ignited,and will rapidly burn toward the case N, where it reaches the powder,causing the same to explode and to separate the parts ot' the cylinder,and also the cord 10, releasing one ofthe levers M, which swings theshaft J to disen gage the cord m, swing the lever G, rotate the shaft F,vibrate the bells C, and also discharge the cannon L. Thorough alarm isthus immediately sounded. A knot, z, on one or each cord, w, may also beapplied to hold back a projecting' arm, a?, from a clock-alarm, O, shownin Fig. 6, so that when the cord w is separated, as aforesaid, the alarmO will be set free to be sounded by the power of its spring. The fuses ymay be utilized to ignite lamps, with which they are connected, so as tostrike light at night. The device may easily be converted into aburglaralarm by connecting the cords lL0, or some of them, with blocksb2, which are iitted upon pins c2 on doorcases, as in Fig. 2, in suchmanner that when the doors are opened they will push the blocks b2 offthe pins o2 and thereby discharge the cords w, releasing the levers Mand sounding' the alarm, as stated.

Having thus described my invention, I claim as new, and desire to secureby Letters Patentl. The bells C G, pivoted frame D, and shaft F,combined as described, and for thepulpose speciied.

2. The combination of the pins h 7L on the wheel e with the levers G, H,and I, all arranged to operate substantially as herein shown anddescribed.

3. The T-head rod j, combined with the bellcrank I, forked lever H,lever G, hook l, and cord m, all arranged substantially as hereinspecied.

4. The barrel L and hammer q, combined with the alarm-Setting apparatusG H I, substantially as herein shown and described.

5. The cord m, secured with one end to the lever I, and with the otherto the hook n ot' the rook-shaft J to operate the alarm Whenever saidrock-shaft is turned, as set forth.

6. The levers M M, combined with the cords w, springs o, rod t, androck-shaft J, to constitute the alarm-discharging apparatus, asspecified.

7. The alarm O, arm a2, and knob z, combined with a cord, w, operated bythe levers M M and rock-shaft J, in the manner speciied.
